Dr. Pengju Ji 吉鹏举:

Dr. Pengju Ji graduated from the University of Huddersfield, UK, with a PhD degree in physical organic chemistry (with Profs. Mike Page and John Atherton), after 2 years postdoc with Prof. Jin-Pei Cheng at Tsinghua University, Beijing, China, he is now a faculty member of the Chemistry Department of Tsinghua University. His research interests mainly cover the solvation and solvent effects of non-aqueous solvents, such as liquid ammonia and more recently ionic liquids. He is also interested with the bond transformation and organic reaction mechanism in these solvents.
